CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to Application No. 60/974,665 filed onSep. 24, 2007, the entire contents of which are incorporated byreference herein.

FIELD OF THE INVENTION

The present invention relates to a fragrance emitting patch that a usercan attach to the body or an article of clothing, and more particularlyto such a patch including at least one layer including a fragrance andan adhesive applied to the patch for selectively securing the patch tothe body or an article of clothing. The present invention also relatesto a compact for holding a plurality of such fragrance emitting patchesin stacked configuration.

BACKGROUND OF THE INVENTION

Fragrance emitting devices are generally used to deliver a pleasingscent to the user. These devices have been used in the past to maskundesirable odors and can also be functionalized with anodor-controlling agent. The prior art discloses fragrance emittingpatches that purport to deliver fragrance when a user attaches the patchonto their body or an article of clothing. These patches generallyinclude one more or more layers of material, at least one of which isprovided with a fragrance. Fragrance emitting patches generally includea positioning adhesive applied to an external surface of the patch forselectively adhering the patch onto the user's skin or article ofclothing. Patches with multiple layers may also include a constructionadhesive used to affix the layers of the patch to one another.

The inventors have discovered that many fragrances used in knownfragrance emitting patches will migrate into the adhesive components ofthe patch and undesirably interact with the adhesive by altering itschemical composition. In particular, the inventors have discovered thearomatic components of many fragrances tend to plasticize the end blocksof standard hot melt adhesives. The inventors have discovered that thisinteraction causes the adhesives to perform poorly by reducing thecohesiveness and internal strength of standard construction andpositioning adhesives. Specifically, the inventors have discovered thatthe interaction between the fragrance and positioning adhesive may causethe patch to detach from the surface to which it is applied and in amultilayer construction the interaction of the fragrance with theconstruction adhesive may cause the undesirable delamination of thelayers of the patch.

The inventors have further discovered that in order for a fragranceemitting patch to provide the desired intensity of scent, and in orderfor the scent to last for a sufficient period of time during use, thefragrance must be applied to the relevant layer of the patch in arelatively high add on amount. However, the inventors have discoveredthat the use of a high add on amount of fragrance exacerbates thedegradation of the adhesive described above.

In view of the foregoing, the present invention provides a fragranceemitting patch that has the ability to incorporate high levels offragrance without sacrificing the functionality of the construction andpositioning adhesives used within the patch.

According to another aspect of the invention, the present invention alsorelates to a compact for carrying a plurality of fragrance emittingpatches in a stacked configuration. The compact permits a plurality ofthe patches to be carried in a convenient portable manner and alsofacilitates the easy removal of a patch from the compact.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, the term “construction adhesive” refers to any adhesivethat is used to join two layers of material to one another.

As used herein, the term “positioning adhesive” refers to any adhesivethat is used to removably attach a fragrance emitting patch to a user'sskin or clothing.

In one embodiment of the invention, the fragrance emitting patchaccording to the present invention is intended to be applied to a user'sundergarment, such as a woman's panty, during use, to thereby provide afresh scent to undergarment. The inventors have found that in order toachieve long lasting fragrance levels that can be detected from theperennial region of the user to the nose, a high amount of fragrancemust be incorporated into the fragrance emitting patch. The inventorshave found that users can detect a product including a fragrance appliedto one of the layers of the patch in an add on amount of greater than 3gsm (g/m²). In one embodiment of the invention, a fragrance is appliedto at least one of the layers of the fragrance emitting patch in anamount of between about 3 gsm and about 15 gsm.

The inventors have discovered that purposely selecting fragrances thatare substantially insoluble in the adhesive compounds used in thefragrance emitting patch minimizes the undesirable reaction betweenthese components. The Hildebrand solubility parameter is used often inchemistry to predict when two solutions are soluble in one another.According to the theory proposed by Dr. Joel Hildebrand, two solutionswill be soluble when the Hildebrand solubility parameter is equal, andinsoluble when the Hildebrand solubility parameter is not equal. Thedifference between the two values is roughly related to the extent ofinsolubility between the two solutions. The Hildebrand solubilityparameter (δ(SI)) is derived from the heat of vaporization (ΔH), theuniversal gas constant (R), the temperature (T), and the molar volume ofthe solution (V_(m)), and is calculated using the following formula:

δ(SI)=[(ΔH−RT)/V _(m)]^(1/2)

The resulting value is a property of a particular solution at a giventemperature. In the international system of units (SI), the universalgas constant (R) is approximately 8.314 J·K⁻¹·mol⁻¹. The Hildebrandsolubility parameter has the units of MPa^(1/2).

The Hildebrand solubility parameter of common adhesives and fragrancesis provided in TABLE 1 below:

According to the present invention, the adhesive(s) and fragrance(s)employed in the fragrance emitting patch have a solubility parameterabsolute value difference of greater than 1.5, preferably greater than3.0 and most preferably greater than 5.0. This relationship can beexpressed by the follow equation:

|δ_(a)−δ_(f)≦1.5; where

-   -   δ_(a)=Hildebrand solubility parameter of the adhesive, and    -   δ_(f)=Hildebrand solubility parameter of the fragrance.        Selection of a fragrance(s) and an adhesive(s) 20 satisfy the        above equation insures that fragrance does not adversly interact        with the ahesive and thereby compromise the same. This insures        that, even at high fragrance add on levels, the fragrance        emitting patch will securely adhere to the surface to which it        is applied and will not delaminate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 illustrates an example of a fragrance emitting patch 10 accordingto the present invention, the patch 10 is adhered to the surface of awoman's undergarment to provide a fresh scent thereto. Referring toFIGS. 2 and 3, the patch 10 includes, according to a first embodiment ofthe invention, a porous primary layer 12 having a top surface 14 and abottom surface 16. The primary layer 12 is provided with a fragrancerepresented by the numeral 18. The fragrance 18 may be applied to a topsurface 14 or bottom 16 surface of the primary layer 12 or it may beinfused into the primary layer 12 itself. The patch 10 is furtherprovided with a positioning adhesive 20 applied to the bottom surface 16of the primary layer 12. The positioning adhesive 20 allows a user toselectively apply the patch to a garment of clothing such as aundergarment, or directly to the skin.

The fragrance emitting patch 10 may be optionally provided with aremovable backing layer 22, shown in FIG. 2, that is intended to protectthe the positioning adhesive 20 prior to use of the patch 10. Thebacking layer 22 may be constructed of a suitable paper and/or polymericfilm material. The surface of the backing layer 22 in contact with thepositioning adhesive 20 may be provided with a non-stick coating such assilicone to facilitate the removal of the backing layer 22 by the userprior to use.

According to one aspect of the invention, the primary layer 12 isconstructed from a porous non-woven web material. The primary layer 12may be composed of only one type of fiber, such as polyester orpolypropylene or it may include a mixture of more than one fiber. Theprimary layer 12 may be composed of bi-component or conjugate fibershaving a low melting point component and a high melting point component.The fibers may be selected from a variety of natural and syntheticmaterials such as nylon, polyester, rayon (in combination with otherfibers), cotton, acrylic fiber and the like and combinations thereof.Preferably, the primary layer 12 has a basis weight in the range ofabout 10 gsm to about 75 gsm. Bi-component fibers may be made up of apolyester layer and a polyethylene sheath. Using a fusible fabricincreases the ease with which the primary layer 12 may be mounted to anyunderlying layer should such an underlying layer be employed. Accordingto another aspect of the invention, the porous primary layer 12 isconstructed from a microporous polymeric film material.

According to one aspect of the invention, the porous primary layer 12 isprovided with the fragrance 18. The fragrance 18 may be selected fromone of the fragrances set forth in Table 1 above or may be selected fromother common fragrances known to those of skill in the art. Thefragrance 18 may also constitute a complex fragrance, i.e. a fragranceincluding a mixture of a number of different fragrance components.Typically the solubility parameter δ_(f) of such complex fragrancemixtures may be obtained from the commercial manufacturer of suchfragrances. The fragrance 18 is preferably provided on or in the primarylayer 12 in an amount greater than about 3 gsm (g/m²), preferablybetween about 3 gsm and about 15 gsm.

According to one aspect of the invention, the bottom surface 16 of theporous primary layer 12 is provided with a positioning adhesive 20.Preferably the positioning adhesive 20 is applied to the bottom surface16 in an amount between about 8 gsm to about 25 gsm. Suitablepositioning adhesive 20 compositions include hot melt adhesives based onblock copolymers such as linear or radial co-polymer structures havingthe formula (A−B)_(x) wherein block A is a polyvinylarene block, block Bis a poly(monoalkenyl) block, and x is an integer greater than or equalto one that denotes the number of polymeric arms. Suitable block Apolyvinylarenes include, but are not limited to, polystyrene,polyalpha-methylstyrene, polyvinyltoluene, and combinations thereof.Likewise, suitable Block B poly(monoalkenyl) blocks include, but are notlimited to, conjugated diene elastomers, such as polybutadiene,polyisoprene, and hydrogenated elastomers such as ethylene butylenes,ethylene propylene, polyisobutylene, or combinations thereof. Commercialexamples of these types of block copolymers include Kraton™ elastomersfrom Kraton Polymers L.P, Vector™ elastomers from Dexco, SIBSTARpolymers from Kaneka USA, and Stereon™ from Firestone Tire & Rubber Co.Alternately, suitable acrylic hot melt adhesive polymers such as theACResin hot melt adhesives from BASF Corp. may also be used. In additionto providing some level of insolubility to the fragrances, these systemscan be rendered further insoluble via crosslinking using a UV radiationsource.

According to the present invention, the positioning adhesive 20 and thefragrance 18 should be selected such that they have a solubilityparameter absolute value difference of greater than 1.5, preferablygreater than 3.0 and most preferably greater than 5.0. This relationshipcan be expressed by the follow equation:

|δ_(pa)−δ_(f)|≦1.5; where

-   -   δ_(pa)=Hildebrand solubility parameter of the positioning        adhesive, and    -   δ_(f)=Hildebrand solubility parameter of the fragrance.        Selection of a fragrance 18 and a positioning adhesive 20 that        satisfy the above equation insures that fragrance 18 does not        adversely interact with the positioning ahesive 20 and thereby        compromise the same. This insures that, even at high fragrance        add on levels, the fragrance emitting patch will securely adhere        to the surface to which it is applied.

Referring to FIGS. 6 and 7, a fragrance emitting patch 10 a includesaccording to another embodiment of the invention, a porous primary layer12 having a top surface 14 and a bottom surface 16. The primary layer 12is provided with a fragrance represented by the numeral 18. Thefragrance 18 may be applied to a top surface 14 or bottom 16 surface ofthe primary layer 12 or it may be infused into the primary layer 12itself. The patch 10 further includes a secondary layer 32 having a topsurface 34 and bottom surface 36. The secondary layer 32 is adhered to abottom surface 16 of the primary layer 12 by a construction adhesive 35that is arranged between the layers 12 and 32. The bottom surface 36 ofthe secondary layer 32 is provided with the positioning adhesive 20 thatpermits a user to selectively apply the patch 10 a to a garment ofclothing such as an undergarment, or directly to the skin.

The construction adhesive 35 is preferably selected from the same groupof adhesives as the positioning adhesive 20. Thus suitable constructionadhesive 35 compositions include hot melt adhesives based on blockcopolymers such as linear or radial co-polymer structures having theformula (A−B)_(x) wherein block A is a polyvinylarene block, block B isa poly(monoalkenyl) block, and x is an integer greater than or equal toone that denotes the number of polymeric arms. Suitable block Apolyvinylarenes include, but are not limited to, polystyrene,polyalphamethylstyrene, polyvinyltoluene, and combinations thereof.Likewise, suitable Block B poly(monoalkenyl) blocks include, but are notlimited to, conjugated diene elastomers, such as polybutadiene,polyisoprene, and hydrogenated elastomers such as ethylene butylenes,ethylene propylene, polyisobutylene, or combinations thereof. Commercialexamples of these types of block copolymers include Kraton™ elastomersfrom Kraton Polymers L.P, Vector™ elastomers from Dexco, SIBSTARpolymers from Kaneka USA, and Stereon™ from Firestone Tire & Rubber Co.Alternately, suitable acrylic hot melt adhesive polymers such as theACResin hot melt adhesives from BASF Corp. may also be used. In additionto providing some level of insolubility to the fragrances, these systemscan be rendered further insoluble via crosslinking using a UV radiationsource.

As shown in FIG. 7, the construction adhesive 35 is preferably appliedto a bottom surface 16 of the primary layer 12 in an amount between 1gsm and 25 gsm. According to an aspect of the invention, theconstruction adhesive 35 and the fragrance 18 are applied in an amountsuch that a ratio of the amount of construction adhesive 35 employed inthe patch 10 a to amount of fragrance 18 incorporated into the patch 10a is between about 0.333 to about 1.67. This relationship can beexpressed by the following equation:

1.67>A _(ca) /A _(f)>0.333, where

-   -   A_(ca)=Add on amount of construction adhesive, and    -   A_(f)=Add on amount of fragrance.

According to the present invention, the construction adhesive 35 and thefragrance 18 should be selected such that they have a solubilityparameter absolute value difference of greater than 1.5, preferablygreater than 3.0 and most preferably greater than 5.0. This relationshipcan be expressed by the follow equation:

|δ_(ca)−δ_(f)|>1.5; where

-   -   δ_(ca)=Hildebrand solubility parameter of the construction        adhesive, and    -   δ_(f)=Hildebrand solubility parameter of the fragrance.        Selection of a fragrance 18 and a construction adhesive 35 that        satisfy the above equation insures that fragrance 18 does not        adversely interact with the construction adhesive 35 and thereby        compromise the same. This insures that, even at high fragrance        add on levels, the layers of the fragrance emitting patch 10 a        will remain secured adhered to one another and will not        delaminate.

According to one aspect of the invention, the secondary layer 32 may bea non-porous layer. In one preferred embodiment of the invention, thesecondary layer 32 is a non-porous polymeric film such as polyethyleneor polypropylene film.

Alternatively, the secondary layer 32 may be a porous layer. A poroussecondary layer 32 may be a nonwoven material composed of only one typeof fiber, such as polyester or polypropylene or it may include a mixtureof more than one fiber. The secondary layer 32 may be composed ofbi-component or conjugate fibers having a low melting point componentand a high melting point component. The fibers may be selected from avariety of natural and synthetic materials such as nylon, polyester,rayon (in combination with other fibers), cotton, acrylic fiber and thelike and combinations thereof. Bi-component fibers may be made up of apolyester layer and a polyethylene sheath. Using a fusible fabricincreases the ease with which the secondary layer 32 may be mounted toan adjacent layer, e.g. the primary layer 12. According to anotheraspect of the invention, the secondary layer 32 is constructed from amicroporous polymeric film material.

Referring to FIGS. 4 and 5, a patch 10 b includes according to a yetanother embodiment of the invention, a porous primary layer 12 having atop surface 14 and a bottom surface 16. The primary layer 12 is providedwith a fragrance represented by the numeral 18. The fragrance 18 may beapplied to a top 14 or bottom 16 surface of the primary layer 12 or itmay be infused into the primary layer 12 itself. The patch 10 b furtherincludes a secondary layer 32 having a top 34 and bottom surface 36. Thebottom surface 36 of the secondary layer 32 is provided with thepositioning adhesive 20 that permits a user to selectively apply thepatch to a garment of clothing such as an undergarment or directly tothe skin.

In the embodiment of the invention shown in FIGS. 4 and 5, the primarylayer 12 is secured to the secondary layer 32 in an adhesive freemanner. For example, the primary layer 12 may be secured to thesecondary layer by embossing using heat and pressure to fuse the primarylayer 12 to the secondary layer 32. The primary layer 12 and secondarylayer 32 may be constructed from nonwoven materials including heatfusible fibers to faciltate the bonding of the layers 12 and 32. In theembodiment shown in FIG. 4 and 5, the patch 10 c includes a bonded area40 around the periphery of the patch 10 b.

The patches 10, 10 a and 10 b described herein preferably have athickness in the range of between about 0.25 mm and about 2.0 mm.
